通过此算法选取出来的阈值非常理想，对各种情况的表现都较为良好。虽然它在很多情况下都不是最佳的分割，但分割质量通常都有一定的保障，可以说是最稳定的分割。由上可知，大津算法是一种较为通用的分割算法。-Through this algorithm to select the threshold by the very satisfactory performance of the various situations are relatively good. Although in many cases it is not the best partition, but the quality of segmentation is usually a certain degree of protection, it can be said is the most stable partition. From the above we can see that Otsu algorithm is a segmentation algorithm is more generic.
